Fostering gratitude is often among the socialization goals parents hold for their children. In this article, we explore work that portrays gratitude as a complex socioemotional process that occurs during a moment in time and becomes more frequent, integrated, and rich with development. Researchers have identified at least four parent socialization practices that may foster children's gratitude: modeling, daily scaffolding, niche selection, and conversations with children about gratitude moments and missed opportunities for gratitude. Parent training tools based on this work have yielded modest results. More work is needed to understand further the ways parenting and children's gratitude are culturally embedded, place the work on gratitude socialization within the larger task of value socialization faced by parents, and explore gratitude as an ontogenetic tool for making meaning of the world around us.
